when she looks like a rugby ball on legs, gets stuck places (due to her fat tum) and you can see the rugby scrum going on in her belly - around a week. having kitties is so exciting! they are so cute and it is an amazing experience. my last lot were born on my lap as my cat purred like a loon. it only gets stressful when they are about five weeks old and they turn your bedroom into a grand prix circuit at 5am or your hubby rolls over in bed and keeps squashing the kitties and you have to rescue them. it gets furry and warm when theres six kitties and a bloke in your bed! best of luck and keep posting if you need advice - oh and provide her with a box or similar enclosed space which she gets used too and hopefully has her bubbies in. never usually works and they pick a daft place to have them ,but it doesn't hurt to try x
